T-Mobile Launches Broadband PTT Service with ESChat
Tuesday, October 15, 2019 | Comments

T-Mobile launched broadband push-to-talk (PTT) service from ESChat on its network. T-Mobile is offering ESChat to its business and government customers without interoperability restrictions, meaning customers purchasing PTT service via T-Mobile can communicate with ESChat users on any other wireless network.

T-Mobile said its PTT service communicates with compatible PTT users on other carriers without the need for hardware gateways or special software versions. T-Mobile PTT users can communicate from anywhere in the world while using Wi-Fi or while roaming.

The PTT service supports Android and iOS smartphones, a limited selection of basic phones and Windows PCs. In addition, all other components of the ESChat ecosystem are also available to T-Mobile customers. These components include LMR integration using radio over IP (RoIP), Project 25 (P25) Inter RF Subsystem Interface (ISSI) and Digital Mobile Radio (DMR) Application Interface Specification (AIS) interfaces, mission-critical call recording/logging using Session Recording Protocol (SIPREC) or span-port interfaces, and CAD and console interfaces using the P25 Console Subsystem Interface (CSSI) and AIS.

Pricing for T-Mobile's PTT service is $5 per month and includes secure PTT, live location tracking and mapping, and secure group multimedia messaging. T-Mobile will invoice customers on their monthly wireless bills.

"We are very pleased to be T-Mobile's technology partner as they enter the PTT market," said Judy King, director of sales, ESChat. "The combination of ESChat's experience and widespread adoption throughout North America, along with T-Mobile's Un-Carrier approach will create a carrier PTT offering that is unique in the U.S. marketplace. T-Mobile has already experienced market success during their soft launch across numerous market verticals, and we look forward to continued growth with general availability.”
